SISTEM TENAGA LISTRIK

1.Sistem Pembangkitan (Generation)2.Sistem Penyaluran (Transmission)

– Penghantar (transmission line)– Gardu Induk (substation)– Pusat Pengatur (Control Centre)

3.Sistem Distribusi (Distribution)

GARDU INDUK

Fungsi GI :– Mentransformasikan daya listrik– Untuk pengaturan pelayanan beban ke GI lain,

dan ke Gardu distribusi– Untuk pengamanan sistem tenaga listrik– Untuk pengawasan operasi (pemantauan,

pengukuran dll)

JENIS-JENIS GI

• Berdasarka tegangannya• Berdasarkan fungsinya• Berdasarkan Isolasi• Berdasarkan sistem rel (Bus bar)

PERALATAN GI

1. Primary Equipment (High Voltage)2. Secondary Equipment (Low Voltage)

PERALATAN GIPrimary Equipment (High Voltage)

– Busbar– Lines– Transformer (Power Transformer, Instrument

Transformer– Kapasitor– Shunt Reactor– Motor– Circuti Breaker– Disconneting Switch– Earthing Switch– Lightning Arrester

PERALATAN GISecondary Equipment (Low Voltage)

– Protection (Distance Relay, Differencial Relay, Eart Fault Relay, Over Current Relay, dll)

– RTU for Monitoring, Control, and measuring– Transducer for measurement (I, kV, MW, MVar, f)– Logger/Recording (event logger, DFR, data logger,

EWS, TWS)– Telecommunication (PLC, Multiplex, PABX)

IMPLEMENTASI GI OTOMASIContoh Implementasi

BENEFIT GI OTOMASI– Less Hardware (panel and cubikle)– Less cabling (hard wire)– Less installation– Less space demand and civil work– Less maintenance (CBM)– One point of data collection (information,

evaluation, analisis)– Economic, effective, and Save Operation and

maintenance– Easy extensions and function implementation

BENEFIT GI OTOMASI– Improve availability due to self-supervision and

redundancy– Reduced cost :

• Installation, commissioning, operation, maintenance, and life-cycle

– No conventional mimic board/panel control– Optical link Reduced EMC – On-line primary equipment monitoring– Open system
